I think I'm going to swap the cam & lifters for a comp XE 262 or 256 and put on another intake that I have.

Side note: I also have an Edelbrock C3BX intake manifold. It actually looks like it's a little more high-rise than the Performer but not quite as tall as the RPM intake. Anyone with any experience with or knowledge of a C3BX? I'm wondering if it would be a compromise between the other two?

I ran the C3BX on my car for a long time with good results before builing up my engine.

When I get the money for gears and stall then I'll swap the XE268 back in there.

I think the torque-ier combo will be alot more fun to drive around town and will be alot quicker off the line with the gearing and stall that are there now.

Appreciate all the suggestions.

Yeah,I understand. Ya cant beat a big stall for coming out of the hole quick,nothing I know will replace that with low gears. I have run rhodes a few times,from what your saying you want I think you will be disappointed. they do help a small amount at best,the price of that small amount it a ticky annoying sound,like a solid except it varies. A little distributer tweaking may help you a little,not what ya want,but maybe better.

rifraf,...what I`m saying is with my 230/234 camshaft it needs a bigger stall than my 2400 stall .....there is just too much room from hitting the gas peddle to the power range. By the time you get to your power range probably 4000rpms you already got smoked. OR more compression will help this out.

Maybe it is a small cam for alot of hot rodders but it still needs the correct combo.

In reply about the 327 crank. Find yourself a cheap 307 as they have the same stroke as the 327's. But I'm no expert in this area and I'm sure we'll get more info from the following posts!

gettin off the subject, but don`t you need a 350 crank then you would have a 377?

I don't understand why your power isn't low now. Thats not that big of a cam. I would be looking more at stuff like how my distributer is advancing myself,is the vacuum hose on the right port etc.

hmm i was planing on a 350 for my camaro. aiming for 13's but guess now i'll take my dads advice and build a 400 destroker 350.
anyone know where i can get a 400 block and a 327 crank?

All this changing cams stuff is a little premature I would think. why not just move the cam around first and see what the engine wants instead of what the driver wants. If there is plenty of p/v clearance,advance the cam 4 degrees. Take a comp test and then move it back 2 degrees and move it around till u get the highest comp reading. You dont even have to have the front of the engine together to do this. Just spin the starter,of course once uve got the rockers back on.You only have to have the ones on #1 so it wont take long to do.

That`s what I was trying to say...more compression...along with a bigger stall....or smaller cam and Rhodes lifters. The power band is tooo high with that cam. I hear so many say that cam is small but as far as I`m concerned and have experienced that small cam needs alot of compression and stall to make a 3200 lb car move with todays standards.

Yes, of the XE274 or XE284, I would use the 274. Personally, I would still go with more compression, unless your wanting to use the cheap grade gas. You have aluminum heads, you could run over 10.1 easy with 93 grade.

so what's the deal with edelbrock alum heads and the XE274H cam ? you guys aren't the only ones complaining ... would the XE284H cam work better with these heads ? (9.25cr)

Not with that Compression. Personally, I would want at least 10:1 with that.

WOW! I just wrote this same post a month or so ago! DV and Luci should remember.....do a search, you should find it.

I agree with you and hear you loud and clear. Everyone says it`s a great combo but......you must have it perfectly tuned and you must have every part of the combo.

This is your post but I must tell you what I have and maybe it`ll help you.

I have the Edelbrock RPM heads, perforemer intake. edelbrock carb 750, 373 rear end and Comp Extreme 274 ( 230/234 @.050 and .490 in and out ). and a 2400 stall. Compression ratio is about 9:7.1.

That combo stinks, the best run I had was a 14.7 ...my 305 ran a 15! I`m sure I could of tweeked it to a 14.2 but I expected low 13`s at worst.

I know what you mean as you need more torque.....my combo would never stop pulling but it just pulled slow and it pulled mostly around 4000 and up.

I had on 1.6 rockers and I went back to 1.5`s...that did help out the low end a little and I also changed the cam timing and that helped out a little. 750 carb and bigger (14 by 3 ) air cleaner also helped a little.

SOOOOOOO...this is what I`m going to do. My engine is all apart now so I`m going to mill the block to bump the compression upto about a 10 : 5 to 1, I may put on a 3000 stall OR go one cam down AND put on the Rhodes lifters. My cash is limited now also so I may go to "Your" cam and put on the rhodes lifters.

I don`t think we would have such a problem if we had roller cams...but I`m learning just like you.

If I were you I would for the time being toss on a .015 head gasket and the lifters. Both cheap. The gasket is weak but it beats a tear down...I`m gonna have it milled cuz it`s already torn down.

I`m, going to everything possible to get more torque, screw the HP...our current combos have plenty of HP but torque moves the car. I`m sure Someone on this board has had the exact same parts as you and I. Recently some one on this board mentioned the exact same thing.....was it you Double V??.....that person mentioned on something to the fact of..street cars should concentrate more on getting more torque.
!!

Let us know what you do ( especially me ) and I will definetly pass it on to what worked for me......it`s frustrating spending $1000 on those heads and have a slow car.
